immediately flush them with a large
quantity of fresh tap water. Have
your eyes examined by a doctor as
soon as possible.
CAUTION
Do not allow brake/clutch fluid to
contact the vehicle's body paint, as
paint damage will result.
Brake/clutch fluid, which has been
exposed to open air for an extended
time should never be used as its
quality cannot be guaranteed. It
should be properly disposed. Don't
put in the wrong kind of fluid. A few
drops of mineral-based oil, such as
engine oil, in your brake/clutch sys-
tem can damage brake/clutch sys-
tem parts.
